Installing 64 bit adobe in firefox

I have 64 bit ubuntu in office and for some strange reasons, it installs 32 bit flash player through apt-get. To install 64 bit version here are the commands to copy paste in terminal.


wget -O flash.tar.gz http://download.macromedia.com/pub/labs/flashplayer10/libflashplayer-10.0.22.87.linux-x86_64.so.tar.gz
tar xvzf flash.tar.gz
mkdir -p ~/.mozilla/plugins
mv libflashplayer.so ~/.mozilla/plugins
pkill firefox
firefox
